MY THEORY FOR CHAPTER SIX Ok, so the fact that copies are in monochrome (like friend inside me) and Friend inside me was most theorized to be in chapter 3, I personally believe Yellow is NOT friend inside me. As chapter five was pretty much a copy of chapter one, we don't see much monochrome. You know what is monochrome? Goners. You know what those are linked to? Gaster. What's Gaster's number? SIX!!!!! YELLOW WILL BE COPIED IN CHAPTER SIX CAUSE OF COURSE THERE IS ANOTHER YELLOW FLOWER AND WE WILL SEE HIM AS THE SECRET BOSS!
His name would be Deputy Gold.
